Aperture - Exposure and ISO form the triangle. Aperture and exposure have on camera dial settings, Why does ISO not, understand film, but not digital since can be changed in menu per need.

If your camera has a programmable button, like the "Fn" button on mine, set that for ISO. I find I don't change ISO often enough to worry about it.

edit: I can also get to ISO from the multi-function in four or five button presses - just as easy as changing the white balance.

Agree - Thanks - Just realized the Landscape, Portrait, Night settings may use both ISO and WB for changes. quote=snowbear]If your camera has a programmable button, like the "Fn" button on mine, set that for ISO. I find I don't change ISO often enough to worry about it.

It depends on the camera. My 50D has a quick-button on the top that shows the ISO range and lets me pick one with the thumbwheel. Just like ISO, exposure, WB and focus type. No biggie.

Thanks for input, considering new camera & features.

Most NIkon cameras have a dedicated ISO button.

Most cameras have an auto ISO setting which works very well MOST OF THE TIME. On many cameras you can set the range that AUTO ISO will use. You need to figure out the parameters that your camera uses to adjust the ISO. On many cameras speeds below 1/50 will cause an increase in the ISO setting. The problems occur when you want or need a ISO higher than what the auto setting will use. The reason is simple, the camera knows when the levels kick in to unacceptable levels or to levels that may require a lot of editing.

Beware of using very high ISO settings. On my Sony NEX 5N the AUTO goes to 3200 with very good results. I have set it to 6400 with good results most of the time. I have even gone to 12800 with OK results but that can be dicey in many conditions.
